Built from high-speed steel (HSS) with a bright, uncoated finish, this tap cuts a 3-48 UNC thread profile and is ground to an H2 thread limit for consistent dimensional control. The plug chamfer, spanning approximately 3 to 5 threads, suits general-purpose tapping in a range of materials including mild steel, aluminum, and plastics. With an overall length of 1-13\/16 inches and a thread length of 1\/2 inch, it fits standard tap holders and drive adapters used in manual and machine tapping operations. Machinists, tool-and-die makers, and maintenance technicians are the primary users of this tap.\u003c\/p\u003e\n\u003cp\u003eThis tap is suited for threading small-diameter fastener holes in light manufacturing, repair, and maintenance applications. The 3-48 UNC coarse-thread designation is common in precision instrument work, electronics enclosures, and small mechanical assemblies where a No. 3 screw is specified. The straight flute design works best in through-holes or shallow blind holes where chips can be backed out or cleared with intermittent reversing. The right-hand thread direction is standard for conventional fastener engagement. Coolant-through capability is not included, so flood or brush-applied cutting fluid is recommended when tapping ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-48 UNC thread form for No. 3 coarse-thread applications in instruments and small assemblies\u003c\/li\u003e\n  \u003cli\u003eHigh-speed steel construction provides adequate hardness and toughness for general-purpose tapping\u003c\/li\u003e\n  \u003cli\u003ePlug chamfer (3-5 thread lead) balances starting ease with thread engagement depth\u003c\/li\u003e\n  \u003cli\u003eH2 thread limit ensures 2B class of fit tolerance compliance for standard nut and fastener mating\u003c\/li\u003e\n  \u003cli\u003eBright, uncoated finish — no coating buildup to affect thread tolerance on small-diameter work\u003c\/li\u003e\n  \u003cli\u003e3-flute design offers good chip clearance relative to tap cross-section at this small diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-use tap for any application requiring a 3-48 UNC, 2B class of fit, plug chamfer straight flute tap in a standard tap holder or T-handle driver.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tap should be installed and driven by a licensed machinist or qualified maintenance technician using a calibrated tap holder, T-handle, or tapping head sized for the shank diameter. Always secure the workpiece before tapping and apply a suitable cutting fluid to reduce friction and heat buildup, particularly in ferrous materials. Back the tap out periodically to break and clear chips, preventing tap breakage in small-diameter holes. Follow shop safety practices and applicable OSHA machine-guarding requirements when operating drill presses or CNC equipment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3-48\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: UNC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Type\u003c\/strong\u003e: Plug\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClass of Fit\u003c\/strong\u003e: 2B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Limit\u003c\/strong\u003e: H2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: High-Speed Steel (HSS)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1.8125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: VALUE COLLECTION\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSC-04423489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"VALUE COLLECTION","offers":[{"title":"Default Title","offer_id":51715927212338,"sku":"MSC-04423489","price":17.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/999183e5b0bb0499554eeadeda25e6dc.jpg?v=1788519836","url":"https:\/\/voomisupply.com\/products\/value-collection-msc-04423489-straight-flute-tap-3-48-unc","provider":"Voomi Supply","version":"1.0","type":"link"}
